3.2 Intended use
The QP 1680-TOC/TNb analyzer is intended for use by individuals who measure water quality
parameters in the laboratory.
3.3 Product overview
The QP 1680-TOC/TNb analyzer measures non-purgeable organic carbon (NPOC) and total bound
nitrogen (TNb) in aqueous samples. The analyzer also measures total carbon (TC), total inorganic
carbon (TIC) and calculates total organic carbon (TOC).
The analyzer has an integrated sampler that analyzes carbon and nitrogen in different water
matrices. The analyzer connects to a PC with the TE Instruments Software (TEIS2) for operation and
automation. Refer to Figure 1 and Figure 2.
